Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a multi-station processing device for a valve body of a gas self-closing valve. Background Art

[0002] Natural gas is a widely used gas fuel. Due to its flammable, explosive, and poisonous properties, leakage can easily cause major safety accidents. Therefore, it is necessary to ensure that the gas entering the gas appliance is maintained at a normal pressure so that it can burn fully and stably. At present, a gas self-closing valve is installed in front of the gas appliance to automatically close the valve in case of overpressure or underpressure to prevent gas leakage. With the increase in functional requirements, some gas self-closing valves will also integrate ball valves and overcurrent cut-off devices, which makes the valve body structure of the gas self-closing valve more complicated. The valve body blanks of the gas self-closing valve are all castings. After obtaining the valve body blank, various drilling or tapping processes are required on the valve body blank. For example Figure 7 The valve body 17 of the gas self-closing valve shown in the figure has a valve port 17a, a cover plate mounting position 17b and a ball valve switch indicator plate mounting position 17d. There are two cover plate mounting holes 17c on the cover plate mounting position 17b, and there is a ball valve indicator plate mounting hole 17e on the ball valve switch indicator plate mounting position 17d. These all need to be processed on the blank.

[0003] For the parts that are processed in the same direction, the current common method is to use a turntable and set processing units corresponding to each process on the edge of the turntable. A fixture for clamping the workpiece is installed on the turntable, and then the turntable rotates so that the workpiece can be processed in the corresponding process by each processing unit in turn. This type of device is also applicable to the valve body of the gas self-closing valve. However, the fixture can usually only clamp workpieces of one specification, so there is a problem of insufficient applicability. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems existing in the prior art and to propose a multi-station processing device for the valve body of a gas self-closing valve, thereby solving the problem of insufficient applicability.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A multi-station processing device for the valve body of a gas self-closing valve comprises a frame, a turntable arranged on the frame, a plurality of processing units fixed on the frame and distributed on the edge of the turntable, and a loading robot and an unloading robot both fixed on the frame. A clamp is provided on the turntable near the edge, and is characterized in that a mounting seat is fixedly connected to the turntable, the clamp comprises a static clamping block fixedly connected to the mounting seat and a dynamic clamping block which can approach or move away from the static clamping block, a clamping cylinder whose piston rod end is fixedly connected to the mounting seat and the dynamic clamping block, a matching groove is provided on the opposite side of the dynamic clamping block and the static clamping block, and when the dynamic clamping block is close to the static clamping block, the two matching grooves can form a positioning cavity that passes through the upper side surface of the clamp and passes through the clamp along the radial direction of the turntable, and an adjustment structure that can adjust the moving distance of the dynamic clamping block in the direction away from the static clamping block is provided between the dynamic clamping block and the mounting seat.

[0007] The loading robot is the loading position, and the clamp at this position is in the open state, that is, the dynamic clamping block and the static clamping block are far away. Of course, at this time, the distance between the dynamic clamping block and the static clamping block will not allow the valve body of the gas self-closing valve to fall out directly. The loading robot clamps the valve body of the gas self-closing valve from the material tray or the loading conveyor belt and conveys it between the dynamic clamping block and the static clamping block. Then the piston rod of the clamping cylinder is pushed out to make the dynamic clamping block approach the static clamping block. The dynamic clamping block and the static clamping block are closed to clamp the valve body of the gas self-closing valve. The matching grooves on the dynamic clamping block and the static clamping block are both against the outer wall of the valve body of the gas self-closing valve. The two ends of the valve body of the gas self-closing valve extend out of the clamp along the radial direction of the turntable. Then, the turntable rotates, so that the clamp performs the corresponding process in each processing unit in turn. After all the processes are completed, the unloading robot clamps the end of the gas self-closing valve body extending out of the fixture, and then the fixture releases the valve body of the gas self-closing valve and the unloading robot takes the clamped gas self-closing valve body out of the fixture to complete automatic unloading.

[0008] The clamping cylinder is used as a driving member for the moving clamping block to be away from the static clamping block, and the adjustment structure is provided, so that the multi-station processing device can load and unload materials normally and can adapt to the processing of valve bodies of gas self-closing valves of various specifications, and has wider applicability. Specifically, when the processing object is a valve body of a gas self-closing valve with smaller specifications, the adjustment structure is adjusted to shorten the distance that the clamping cylinder drives the moving clamping block away from the static clamping block; when the processing object is a valve body of a gas self-closing valve with larger specifications, the adjustment structure is adjusted to lengthen the distance that the clamping cylinder drives the moving clamping block away from the static clamping block.

[0009] In the above-mentioned multi-station processing device for the valve body of the gas self-closing valve, the mounting seat includes a base plate and a vertical plate fixedly connected to the base plate, the dynamic clamping block is located between the static clamping block and the vertical plate, the clamping cylinder is arranged on the vertical plate, a guide rod is fixedly connected between the static clamping block and the vertical plate, the guide rod passes through the dynamic clamping block and a linear bearing is arranged between the two.

[0010] Through the above arrangement, the movement of the dynamic clamping block is smoother and the clamp is not easily obstructed when opening and closing.

[0011] In the above-mentioned multi-station processing device for the valve body of the gas self-closing valve, the adjustment structure includes an adjustment screw threadedly connected to the vertical plate and a side of the movable clamping block facing the vertical plate, and the end of the adjustment screw abuts against the side of the movable clamping block facing the vertical plate.

[0012] When the valve body of the processed gas self-closing valve has a larger specification, the adjusting screw is turned to shorten the distance that the end thereof protrudes from the vertical plate toward the side of the dynamic clamping block, so that the moving distance of the dynamic clamping block away from the static clamping block is relatively large; when the valve body of the processed gas self-closing valve has a smaller specification, the adjusting screw is turned to lengthen the distance that the end thereof protrudes from the vertical plate toward the side of the dynamic clamping block, so that the moving distance of the dynamic clamping block away from the static clamping block is relatively short.

[0013] In the above-mentioned multi-station processing device for the valve body of the gas self-closing valve, as another technical solution, the adjustment structure includes an adjustment screw threadedly connected to the side of the movable clamping block facing the vertical plate and a side of the vertical plate facing the movable clamping block, and the end of the adjustment screw abuts against the side of the vertical plate facing the movable clamping block.

[0014] When the valve body of the processed gas self-closing valve has a larger specification, the adjusting screw is turned to shorten the distance that the end thereof extends out of the movable clamping block toward the side of the vertical plate, so that the moving distance of the movable clamping block away from the static clamping block is relatively large; when the valve body of the processed gas self-closing valve has a smaller specification, the adjusting screw is turned to lengthen the distance that the end thereof extends out of the movable clamping block toward the side of the vertical plate, so that the moving distance of the movable clamping block away from the static clamping block is relatively short.

[0015] In the above-mentioned multi-station processing device for the valve body of the gas self-closing valve, a material unloading conveyor belt is also fixedly connected to the frame, and the material unloading conveyor belt is located on one side of the material unloading manipulator.

[0016] The setting of the unloading conveyor belt can automatically remove the valve body of the gas self-closing valve from the fixture after the processing is completed and transfer it to the next process.

[0017] In the above-mentioned multi-station processing device for the valve body of the gas self-closing valve, the number of the clamps is eight and the number of mounting seats is the same as the clamps, the number of processing units is six and the processing units are respectively a valve port deburring unit, a cover plate mounting position deburring unit, a cover plate mounting position small hole drilling unit, a ball valve switch indicator plate mounting position small hole drilling unit, a ball valve switch indicator plate mounting position small hole tapping unit and a cover plate mounting position small hole tapping unit, the loading robot is adjacent to the valve port deburring unit, and the unloading robot is adjacent to the cover plate mounting position small hole tapping unit.

[0018] Compared with the prior art, the multi-station processing device for the valve body of the gas self-closing valve adopts a clamping cylinder as a driving part for moving the dynamic clamping block away from the static clamping block, and cooperates with the setting of the upper adjustment structure, so that it can automatically load and unload materials normally while being able to adapt to the processing of valve bodies of gas self-closing valves of various specifications, and has a wider applicability.
